Apple blacking out vacation days during second week of October

Apple is quietly denying requests for employee vacations during the second week of October, hinting that the company currently anticipates an influx of customers to its stores around that time related to availability of its new iOS 5 and fifth-generation iPhone products.

More specifically, the iPhone maker has in some locations blacked out vacation time for employees from October 9th through 12th and October 14th through 15th, according to people familiar with the matter.

Potential iOS 5.0 Release Date

The first block of dates —the 9th through the 12 —could pertain to the release of iOS 5 for existing iOS device owners on Monday the 10th. As AppleInsider reported last week, certain segments of the company's AppleCare divisions have been told to prepare for an influx of iOS-related inquiries on that same day.

Twitter has also scheduled a developer event and a pair of "Developer Teatimes" for Oct. 10 and Oct. 12 with a "heavy focus" on the social service's tight integration with iOS 5, further suggesting that Apple's non-disclosure terms covering the new mobile OS will have been lifted by then via a public release of the software.

Issuing a major iOS release a few days prior to launching new iPhone that will also leverage the software is not unexpected. For instance, last year Apple released iOS 4.0 on June 21st and then rolled out the iPhone 4 on June 24th. And a year earlier it launched iOS 3.0 (then dubbed iPhone Software 3.0) on June 17th and then followed up with the iPhone 3GS on the 21st.

Potential iPhone 5 Release Weekend

Assuming hints of an iOS 5.0 release around Monday, October 10th prove accurate, the second block of retail blackout dates —October 14th and 15th —could signal availability of the fifth-generation iPhone hardware by that Friday.

With Apple rumored to hold a media event to first unveil its fifth-generation iPhone plans on October 4th, that would give the Cupertino-based company roughly 10 days to field pre-orders ahead of an official launch.
